Structure of multifunctional scooter

ABSTRACT

An improved structure of multifunctional scooter mainly comprises of a axle base centered with a long hole and respectively connected with the fastening frames on the two sides, two wheel axles projecting from the outer sides of the fastening frames for pivotally jointing the front sliding wheels, the front ski board or the front ice skating blade, furthermore, a connect link jointed to the said rigid axle to allow the vertical rigid axle on the front end of the footboard to go through the said axle base and connect a drive link to the two bottom ends of the two rigid axles; a rear sliding wheel, a rear ski board or a rear ice skating blade disposed on the posterior aspect of the footboard to allow the player while stepping on the footboard surface and sliding on the ground, the snow or the ice to be able to step on the two sides of the footboard to make the rigid axles to deflect leftward or rightward to achieve the controlling of the travel directions of the scooter.

BACKGROUND OF THE INVENTION

[0001] 1) Field of the Invention

[0002] The invention herein relates to an improved structure of multifunctional scooter, more specifically, a scooter structure controlling the sliding directions by feet is capable of simple operation and responsive turning.

[0003] 2) Description of the Prior Art

[0004] As widely known, the conventional scooter shown in FIGS. 1 and 2, as the isometric drawings of the embodiment during utilization and of partial structure, mainly comprises of a spherical handle 41, a topside stem 4, a mounting device 46, a splayed forward frame 40, front wheels 42, a footboard 44, a rear wheel 43, and springs 45, of which the splayed forward frame 40 is disposed at the anterior aspect of the footboard 44 and mounted to each of its two sides is a wheel block 400 that provides for the installation of the front wheels 42, and situated in the center area of the splayed frame 40 are compression springs 45, each positioned against the interior sides of a wheel block 400; the topside stem 4 is disposed at the upper extent of the splayed forward frame 40 and a spherical handle 41 for manual grasping positioned at the upper end of the topside stem 4, and a mounting device 46 is situated between the splayed forward frame 40 and the topside stem 4; and a single rear wheel 43 is installed in the center posterior aspect of the footboard 44; since the structural design of the conventional product is not sound, its operation involves the manual grasping of the spherical handle 41 of the topside stem 4 to control the scooter to turn left or right, as such, when the topside stem 4 is leaned to one side, this results in the application of pressure against the wheel at one side of the front wheels 42 which causes the springs 45 on one side to compress and alter direction, but since the wheel on the other side of the front wheels 42 continues in a straight line, both of the two front wheels 42 are incapable of effectively deflecting synchronously, resulting not only in rough and unresponsive operating control but also diminishes the usable service life.

SUMMARY OF THE INVENTION

[0005] Therefore, the primary objective of the invention herein is to provide an improved structure of a multifunctional scooter capable of allowing the user, while stepping on the surface of the footboard to slide, to control the travel direction of the scooter by stepping on both sides of the footboard to make the front wheels deflect towards the same direction in smooth turning and responsive operation.

[0006] Another objective of the invention herein is to provide wheel axles of the front and rear wheels of the scooter capable of pivotally jointing the ski board or the ice skating blade to enable the scooter to slide on the snow or the ice thus to increase its practical value.

[0007] To enable a further understanding of the main features and the innovative aspects of the invention herein, the brief description of the drawings below is followed by the detailed description of the preferred embodiments.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] Referring to FIGS. 3 and 4, as the pictorial, exploded and isometric drawings of the invention herein, the invention herein, like the conventional scooter (1), mainly comprises a handle bar (41), a footboard (44) and a rear wheel (43), wherein a rigid axle (2) is disposed at the front end of the footboard (44) and inserted to the long hole (30) situated at the center of the axle base (3) positioned at the lower edge of the front end of the footboard (44); both ends of the axle base (3) deflect and extend with sleeve holes (31) disposed respectively on the end heads for framing the two fastening frames (5) shown in FIG. 5 as the isometric drawing of the connection between the axle base and the fastening frame of the invention herein. First, the two sliding sleeves (33) will be sleeved into the top and bottom ends on the sleeve holes (31), then the fastening frames (5) will be framed to insert the fastening screws (51) into the sliding sleeves (33) and the sleeve holes (31) to fasten the fastening frames (5) and the axle base (3) reciprocally.

[0017] The wheel axles (52) protrude from the outer sides of the two fastening frames (5) for pivotally jointing two front wheels (53), while two block bodies (34) project from the front end at the center of the axle base (3) for telescoping a connect link (6) and two springs (61) on the connect link (6) to link its both ends respectively to the front ends of the fastening frames (5) and to take the two block bodies (34) as the positioning support points.

[0018] After being inserted into the long hole (30) of the axle base (3), the two rigid axles (2) are pivotally jointed to the fastening panel (71) centered on the drive link (7) with nuts (70) on both ends and link the tow ends of the drive link (7) with the bottom ends of the two fastening frames (5).

[0019] A fastening pole (8) with notches (81) on both front and rear edges is situated on the upper aspect of the front end of the footboard (44) to allow the handle bar (41) after going through a lock ring (9) to be locked to the fastening pole (8) and positioned by the upper and lower locks of the lock ring (9) to stay vertically or horizontally for the player to manually control the scooter (1) or to ship by carrying it.

[0020] By utilizing the assembly of the foregoing structure, the player can manually hold the handle bar (41) and step the foot on the footboard (44) to constitute the sliding movement; while stepping the foot on the two sides of the footboard (44), due to the left and the right deflections caused by the rigid axle (2), the drive link (7) and the connect link (6) will relatively deflect to the same direction to achieve the function of controlling the direction turning of the scooter (1) and correcting the positioning of the front wheels (53) through the adjusting rotation of the nuts (70) on the drive link (7).

[0021] Referring to FIG. 6, as an isometric drawing of the front wheel in action of the invention herein, to turn left or right of the invention herein while the left or the right sides of the footboard (44) being stepped on is controlled by the left or right deflection caused by the rigid axle (2) connected at the lower aspect of the footboard (44), which relatively makes the drive link (7) pull the fastening frames (5) to deflect to the same direction and takes the connect link (6) as the support point to deflect the front wheels (53) to the direction of being stepped, therefore, the whole scooter (1) achieve the objective of turning along the same direction; however, when the footboard (44) is in stable condition, the axle base (3) will resume to the original position due to the elasticity of the springs (61), so the front wheels (53) will be straightened and move in straight lines retentively.

[0022] Referring to FIG. 7, an isometric drawing of another assembly of the invention herein in embodiment, the front and rear wheels (53, 43) can be disassembled to pivotally mount the triangular fastening block (55) of the ski board (54) to enable the scooter (1) to slide on the snow; referring to FIG. 8, another isometric drawing of another assembly of the invention herein in embodiment, the triangular fastening block (57) of the ice skating blade (56) can also be pivotally mounted to the positions of the front and rear wheels (53, 43) to enable the scooter (1) to slide on the ice, so that the scooter (1) can also move in the winter thus to enhance its practical value.

[0023] In summation of the foregoing section, the invention herein fully complies with new patent requirements and is hereby submitted to the patent bureau for review and the granting of the commensurate patent rights.
